since last year we have a RUTX11 in our camper. Some pages have connections issues, others are working fine.
For example I can watch Youtube without problems, opening Ebay does not work reliably. If I connect to a Wireguard-VPN to our home everything works fine.
A speedtest using speedtest.net often reports a very bad upload (<1 Mbit, sometime 0MBit, with VPN >20Mbit)
We are using a SIM-Card from Deutsche Telekom with an unlimited plan.
Does anybody have the same problems?
